1 Claim. (Cl..206,--62) This invention appertains. to shipping cartonsfor the curved rear windows and Windshields of automobiles of theso-called Panoramic or wrap-around type.

As brought out in my co-pending applications Serial Numbers 411,991 and515,394, filed respectively on May 8, 1954, and June 14', 1955, and nowPatent Nos. 2,771,091 and 2,812,855, much difliculty is experienced inthe proper packaging of the curved rear windows and Windshields ofautomobiles, so as to prevent breakage thereof during shipping andhandling.

One of the primary objects of my present invention is the provision ofnovel means forming a. direct part of the carton for encircling theglass as the same is placed in the carton to provide an effectiveprotection for the central part of the glass and,,for preventing lateralshifting of the glass in the, carton. and thus prevent undue strains onthe curved terminals. of the glass.

Another salient, object of, my invention is to provide means carried bythe body portion of the carton for encircling the central portion of theglass being shipped and for snugly engaging the longitudinal edges ofthe packaging strip placed about the edge of the glass, whereby thestrip will be held in proper position at all times relative to the glassirrespective of the position of the carton during handling and shipping.

A further important object of my invention is the provision of portionscut out from the top and bottom of the sealing flaps of the carton forinterconnection when said portions are folded about the windshield withthe portions disposed an exact distance from one of the side walls ofthe carton, so that the portions in conjunction with the side wall willeffectively hold the glass in place and the packaging strip extendingabout the glass.

With these and other objects in "view, the invention consists in thenovel construction, arrangement and formation of parts as will behereinafter more specifically described and claimed and illustrated inthe accompanying drawings, in which drawings,

Figure 1 is a top plan View of my improved carton with the top flaps intheir open position to expose to view the curved glass with thepackaging strip thereabout and the inwardly folded wings encircling thecentral portion of the glass, parts of the top flaps being shown brokenaway;

Figure 2 is a fragmentary longitudinal sectional view through the cartontaken on the line 22 of Figure 1, looking in the direction of thearrows, the view showing the wings encircling the glass, a part of oneof the wings being shown broken away;

Figure 3 is a fragmentary transverse sectional view through the cartontaken on the line 33 of Figure 2, looking in the direction of thearrows;

Figure 4 is a perspective view of the carton showing the same in itsopen condition;

Figure 5 is a perspective View of the carton showing the same in itspartially opened position;

Figure 6 is a perspective view of the carton showing the same in itscompletely closed, sealed position, and

Figure 7 is a plan view of the blank from which the carton can be made.

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several views,the letter C generally indicates my improved carton and B (see Fig. 7) ablank from which the carton can be formed.

The carton C includes like side walls 10 and 11 connected by an end wall12. As shown in Figure 7 the blank is scored transversely, as at 13 and14, to define the end wall 12. One transverse edge of the side wall 10has formed thereon the opposite end wall 15 and this end wall is definedby a transverse score line 16-.

Referring more particularly to the blank B it can be seen that the blankis folded on the lines 13 and 14 and then on the line 16 and this willprovide the body portion of the carton of an oblong shape. At this time,the free edge of the end wall 15 can be secured to the free edge of theside wall 11 by heavy adhesive tape. Formed on the longitudinal edges ofthe side wall 10 and defined by longitudinal score lines 17 are innertop and bottom closure flaps 18 and 19. These flaps 18 and 19 aretreated in a particular fashion, as will be later brought out so as togive my desired means for protecting the windshield. Obviously, theseflaps 18 and 19 are folded at right angles on the score lines 17 to theside wall 119 to form the desired inner top and bottom flaps. Formed onthe longitudinal edges of the side wall 11 are top and bottom closureflaps 29 and 21. It can be seen that the score lines 17 are continuedthe entire length of the blank B and hence the outer flaps 20 and 21 arealso bent at right angles to their side wall 11, on the score lines 17.The outer transverse edges of the end Wall 12 have formed thereon topand bottom end closure flaps 22 and 23, and these flaps are also foldedat right angles on the score lines 17. Formed on the transverse edges ofthe end wall 15 are top and bottom end flaps 24 and 25 and these endflaps are also folded at right angles to the end Wall 15 on thelongitudinal score lines 17. The top and bottom end flaps 22, 23, 24 and25 are also defined by transversely extending slits 26 which extend fromthe longitudinal edges of the blank B to the score lines 17 and theseslits 26 separate the end flaps from the top and bottom flaps '18, 19,20 and 21.

Now referring more particularly to the present in vention, the inner topand bottom side flaps 18 and 19 are provided with transverse slits 27,and these slits 27 also extend from the longitudinal edges of the blankto the score lines 17 and these slits 27 define therebetween foldabletop and bottom wings 28 and 29. These wings 28 and 29 are locatedcentrally of the carton when the blank is folded into proper form, aswill now appear. It is to be noted that the wings 28 and 29 are scoredon longitudinally extending lines '30 in close but spaced parallelrelation to the score lines 17 and this will now be referred to. Thewings 28 and 29 are folded, in setting up the carton from the blank B,first at right angles to the wall 10 on the score lines 17, after whichthe wings are again folded at right angles on the score line 30 and thisdefines a spacer wall 31. As previously stated, the blank B is folded onthe score lines 13, 14 and 16 so as to bring the side walls 10 and 1 1in spaced parallel relation to one another and the end walls 14 and 15in spaced parallel relation to one another, and after which side wallflap 21 is folded over and secured in place. This completes the bottomwall of the carton and the curved rear window W or windshield, as thecase may be, is placed in the carton with a packaging strip 32 placedaround the edges thereof. This packaging strip can be of the type shownin my pending applications and this strip forms no part of the presentinvention. With the windshield W in place, as best shown in Figures 1, 2and 3, the wings 28 and 29 are folded inwardly toward one another aroundthe windshield and are secured togeth r in any desired way, such as byan adhesive or by wire staples. The end top flaps 22 and 24 are nowfolded down over the windshield and rest upon the upper spacer wall 31of the Wing 28 and this spacer wall forms an eflicient support for theseend flaps. The remaining portions of the inner side flaps 13 are nowfolded down over the end flaps 22 and 24 and when this is accomplished,the outer side flap 29 is folded down and sealed in place, as best shownin Figure 6.

Now referring back to Figures 1, 2 and 3 the spacer walls 31 of thewings 23 and 29 are of an exact width so that the packaging strip 32will be confined between the wings 28 and 29 and the side wall and thusthe packaging strip throughout a good portion of its length will be heldin place against lateral shifting movement and consequently thewindshield or rear window W will also be held in place against lateralshifting movement. Not only do the wings 28 and 29 form means forsupporting the end flaps 22, 23, 24 and 25, but they also form means forholding the packaging strip 32 in place and a general protection for thecentral part of the windshield. As the glass is held against lateralmovement, stress is also prevented on the end terminals of the glasswhich would be caused by shifting of the glass in the carton.

From the foregoing description, it can be seen that I have provided anovel and efficient means for packaging and preventing breakage ofcurved automobile glass and that the protecting means is formed from adirect part of the carton, thereby eliminating the expense offabrieating extraneous protecting members.

Changes in details may be made without departing from the spirit or thescope of this invention, but what I claim as new is:

A package for shipping curved glass of the panoramic windshield typecomprising a carton, a curved windshield in the carton including a maincurved body portion and curved back terminals, the carton includingside, end, top and bottom walls, a part of the body portion of thewindshield lying adjacent to and substantially parallel with one sidewall, said top and bottom walls each including inner and outer foldableoverlapping side flaps, said inner side flaps having spaced transverselyextending slits intermediate their ends and centrally disposed foldingwings defined by the slits bent at right angles to the major portion ofthe inner side flaps and parallel to the mentioned side wall and overthe part of the body portion of the glass .lying adjacent to thementioned side wall to confine the body portion of the glass between thementioned side Wall and the wings, and said foldable wings having topand bottom spacer walls uniting the same with the mentioned side wallwhereby to space the major portions of the wings an exact distance fromsaid side wall.
